UNITED STATES JOHN GEORGE HAUS, F WEIRTON, WEST VIRGIN IA.

WATER HEATER.

Application filed. April 22, 1924. Serial No. 715,258.

To all whom it may concern v Be it known that I, JoHNGr Hans, a ,citizen of the United States, and a resident of Weirton, in the county of Hancock and State of West Virginia, have invented a new and Improved Water Heater, of which the following is a full, clear, and exact description. This invention relates to water" heaters 19 and more particularly to water heaters for domestic uses, although, of course, the invention is not limited to the particular use, an object of the invention being to provide a water heater'which may be connected to a domestic boiler by tank and which will uickly and economically heat the water in t e bo1ler or tank. I A further object is to provide an improved construction of heating unit especially designed for use in connection with a gas burner, which unit insures a circulation of the water in a relatively small stream so that in its passa e through the unit it is heated to a high egree and returned to the boiler from whence it came in a highly heated condition. 1

A further object is to rovide a water heater which may berea ily installed in connection with ordinary domestic boilers, so which will result in .an economy of space and which will most efliciently perform the functions for which it is intended.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts which will be more fully hereinafter described and pointed out in the claim. 4

In the accompanying drawings- 7 Figure 1 is a' view, mainly in longitudinal section but partly in elevation, illustrating m improved water heater in connection with an ordinary domestic boiler;

Figure 2 is an enlarged view in transverse 46 section on the line 2--2 of Figure 1;

Figure 3 is a similar view in section on the hue 33 of Figure 1;

Figure 4 is a view in transverse or horizontal section through the water heating unit, the view being taken on the line 44 of Figure 5;

Fi re 5 is an enlarged view in vertical section through the lower portion of the boiler and the heating unit;

Figure 6 is a fragmentary detailed view illustrating the manner of connecting the heating unit to a boiler support.

1 represents a boiler, 2 an inlet pipe which projects to a point adjacent the bottom of the'boiler for supplying cold Water thereto,

and 3 is an outlet pipe'for carrying ofl' hot I boilers may be provided with flat bottoms,

concave bottoms or convex bottoms, and hence to properly locate the unit provision must be made for adjustment thereof relative to the feet or legs of the boiler.

The heating unit 5 is preferably of cylindrical form and at its upper end is made A with a sleeve 9 which has screw-threaded engagement, as shown at 10, with a nipple 11 constituting an outlet for the bottom of the boiler 1. At the top or theu per portion of the heating unit 5 I provi e a heating chamber 12 in which a vertical partition 13 is located forming the chamber 12 into a relatively long circuitous passage, the inlet 14 of which is located at the periphery of the chamber and is connected by a passage 15 with the nipple 11 of the boiler 1.

The outlet ofsaid chamber 12 which is at the center thereof communicates with a vertical tube 16, preferably screwed into athreaded nipple 17 at the center of the chamber 12. This tube 17 is appreciably smaller than the nipple 11, is projected centrally therethrough, and extends up into the boiler apron is made with outlets 22 in its wall to allow for the necessary draft and to permit the heating units to pass upwardly and around the heater and against the bottom of the boiler. to assist in raising the temperature of the water. Thisburner- 21 preferably constitutes a gas burner although, of course, it is to be understood that the invention is not limited to the particular type of burner or to the fuel employed as it is obvious'that oil, electricity or other heating means may be ,employed.

A drain cock 23 communicates with the inlet 14 of chamber 12 so as to drain ofi the water from the heating unit and from the ':boiler as well whenever occasion may require.

In operation, cold water from the boiler 1 flows downwardly through nipple 11, passage 15 intoinlet 14 and thence travels in a circuitous path through the chamber 12 where it is subjected to the intense heat of the burner 21. The water after its passage through the chamber 12 enters pipe 16 and is discharged into the upper portion of the boiler 1.

While I have illustrated what I believe to be a preferred embodiment of my invention it is obvious that various slight changes and alterations as fairly fall within the spirit and scope of the appended claim may be made.

I claim: A water heater, comprising upper and lower plates, a partition connecting said plates and forming a thin circuitous water chamber or passage having its inlet and out let at its outer and central portions, said heater having a depending apron perforated adjacent the lower plate of the heater and adapted to receive a burner confined within the apron, said perforations constituting an outlet for air admitted through the bottom of the open apron, lugs projecting radially from the apron, and means for adjustably securing said lugs to the legs of a boiler.
